Question

I create class A that extends “AdapterView<ListAdapter>”, and create class D that extends “BaseAdapter” providing the data.

The problem is that every AdapterView item is not stretching its length to AdapterView’s length, and the length of each item is different as it is the same as the length of the text in the item. I set all layout parameters I can set to “FILL_PARENT”, but that does not make sense.

Which class should I check? The AdapterView subclass, or the BaseAdapter subclass, or the TextView subclass in AdapterView item? (I subclass TextView to get some extra effect).

The getView methods:

public View getView(int position, View convertView, ViewGroup viewGroup) {

    ViewHolder holder;
    if (convertView == null) {
        convertView = LayoutInflater.from(context).inflate(
                R.layout.colselector_menu_item, null);
        holder = new ViewHolder();

        convertView.setTag(holder);

        TextView tv = new VerticalTextView(viewGroup.getContext());
        tv.setTextColor(Color.RED);

        NewsInTimeApp app = (NewsInTimeApp) (((MainActivity) context)
                .getApplication());
        tv.setTextSize(Integer.parseInt(app.getConfig().get(
                AppConfig.CFGNAME_UI_MAIN_COLSELECTOR_TEXTSIZE)));
        ((LinearLayout) convertView).addView(tv);
        holder.groupItem = tv;

    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    holder.groupItem.setText(list.get(position).getName());
    holder.collId = list.get(position).getId();

    return convertView;
}

The colselector_menu_item.xml :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#e1e1e1"
android:orientation="horizontal" >

<View
android:layout_width="1dp"
android:layout_height="fill_parent"
android:background="@android:color/darker_gray"/>

</LinearLayout>

When you are adding the view, you’re not specifying any layout parameters for the TextView itself.

Try:

(LinearLayout) convertView.addView(tv, LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

If targeting API<8, change MATCH_PARENT to FILL_PARENT. This also assumes you do want them to wrap content vertically.
